Another update! I am moving into a house that I just bought and building a huge testing labratory/film studio. I will have some really awesome systems and explanation videos coming :) I am a bit behind on videos right now for this reason, but will be uploading a lot more in the weeks to come. Stay tuned :D
Cool video suggestion: when then battery is attached; there is a spark. Even if you use a switch, there's internal current surge. I think there's a capacitor charging. So if we all used a resistor and diode properly attached, the sparking and current surge that's bad for electronic boards could be eliminated. That woul be an awesome video and Gizmo to sell from your website. Thanks Jack
Congrats, Will. I've been hoping your vids might start moving that direction---DIY home systems. Great! Looking forward to your future vids even more now!
I'm part of a couple off-grid facebook groups. Any time someone posts a question about solar, everyone responds with links to your videos. I can't think of another channel that comes close to being as thorough or comprehensive. Thank you
If you had a solar installation company I would totally buy its services! Will you are such an honest and quality focused person. Thank you for your videos!
Its great the market is creating these quality easy to install systems. It shows the marketplace is maturing and solar is becoming even more accessible and accepted.
Hello l just discovered your channel that's amazing to follow but l have a question is about my house not in America but outside how many solar panels l need for 4 rooms including yard front house tell me please how many watts and batteries generally explain me for all how many powers
I have been researching solar for about a year now contemplating a grid tied system for our house and to charge my Chevy Volt. The all in one systems are making this look so doable without the hassle of picking components, getting them wired and then commissioning the system. I've been a technology professional for 25 years so I can appreciate complexity, but simpler is definitely better in this case! Keep up the informative easy to follow videos that have become my go to source for DIY solar/battery systems. Looking forward to the larger 5k system review.
Grab a 1 ohm 25 watt resistor to arrest the spark when connecting batteries to the inverter unit. It's kinder to the capacitors in the inveter. Put the resistor inline for 5 seconds, then move the battery cable to the battery terminal, and throw the resistor in a drawer for the next inverter you plan to play with :)
Hey dash8brj! Thanks for the tip! Sorry for my bad english but i did not get it when you said inline for five seconds. Could you explain that? Inline means between the battery positive and the positive wire? Thank you so much!
Some inverters, PSUs, and other gear sometimes do have internal inrush current protection. These are usually done using a resistor in series, and a bypass relay, that energizes only after unit charged capacitors enough. It is usually just using few seconds delay. If the unit doesn't have it, I recommend sticking a DC two disconnect switches in parallel, and one of them via the resistor. Definitively good to have if you have very big system or you plan to be changing batteries frequently, and stuff.
dash8brj Our company's micro-inverters are all upgraded and no longer need Modem! ！ Can directly mobile phone intelligent monitoring, more understanding of technology can add me whatsapp 8613927402025
I want to create a little solar system with my 12 yr old daughter to give her some experience. This might be something we can use to create an off grid bedroom to run her electronics. Very cool.
"And here's the batteries we'll be getting. No, you only need two. No you can't get ten. Because you're not going to be playing video games all night. Because I said so!"
I purchased the MPP 2400w model, and I can't wait to get started on my solar build. Just saving up for those Battleborns. Will, your passion for Solar arrays has helped so many people. Thank you for all of the great information.
I do not like battery cut off switches because if someone switches the switch to open, and the unit is connected to a string of panels, it can destroy the mppt board. I prefer hardwire battery, and switch at the panels for maintenance.
@@WillProwse That's a good point. How do grid tied systems deal with this? The types that feed back into the grid. They can be shut off at any time by the electric company.
Might be wise to mention the AC cable size requirement for full load. Minimum 16 gauge for the 120V size and it will probably warm up and is only going to be good for a very short run. For instance the 16 gauge cord you are using is only rated up to 13 amps most of the time, 2600 watts @ 120V is closer to 22 amps. If you are going to be using full load 10 gauge is a much better idea and the power outlet you plug that in to if you will potentially be pulling over 2600 watts from the grid should be a 30 amp breaker with a cord and outlets to match. When you start using the systems you not only have to calculate the loads the system can handle and the wire size for the DC side but also the AC side under full load. That system can power a decent sized RV that likely has a 30 Amp cord. Would hate to hear of someone burning their home or shop down due to undersized AC cords.
I figure it is implied but this is a beginner video. I do assume that beginners understand wire gauge size for their loads, but always a great idea to mention it in these videos. thanks John
@@WillProwse Yeah, it might be worth mentioning though that the person doing the work should look up the wire sizes needed for their loading. It's hard to believe what some people will try and run through a little 18 gauge cord. People with electricity are like cats and boxes, if it fits it works...
I believe he is 26 years old and makes almost all of his money off of the youtube videos. He was surprised that I have 10 college degrees and he has none. He was very polite when we comunicated.
At the start i had a 12 volt system , then at the end went 48v for the main reasons that it runs a lot more efficient and cool , the amp draw is alot easier on the system ...
Perfect. Stand alone, no ‘daily ‘supply fee.’ ( connected fee from utilities: regardless of using it or not ). AC in can be a small cheap ‘stand alone ‘ generator to boost a low battery supply. 👍
12 years ago we bought a small 1300sf home with a basement and walk-in attic. I bought a 220w 12-18 volt DC and a 400w wind turbine. I also bought 12- group 31 deep-cycle batteries. The panel, turbine, and batteries were 40 ft from the house. I ran a + and - run using 4ga high-strand wier about a foot underground through 1.5 pvc s40 to the house where I had a 8 block fuse box and 2 3000w TS-inverts. in the basement, I then wired a 110 plugin ever-room and 2 110 in the living room. We used the13w=75 watt 110 bulbs in each light we used the most at night and in the kitchen we used/installed 12v under cabinet RV light under all the cabinets. The house box was never touched and the battery power was independent. At that time it cost me $3,100 and we have been saving a 3rd of our elect bill since and without changing our lifestyle or habits. O, I also run most of all my shop radios, bench, equipment as well
Please do video that shows how to do a van conversion setup with this where you need 12v and 110v, how do the wires get attached and wall plugs/sockets light switch etc
i got shocked with 220 the other day wasn't all that bad, accidental touch real quick, working on a/c condenser motor, got it working by watching these videos.
Will, please talk about using Nissan Leaf batteries in conjunction with these controllers in 48 volts to use in home systems. This channel is awesome and very helpful. No bs just facts and real world approach....thanks .
This video has helped me lots. I am going to be building a 48v system for my house. I am terminally ill the system isn't for me its for my family after I pass away I want to make sure my family is well cared for regardless of what happens in the future they will have the power to run our home all the time that's what's important to me. Thanks much!!
Ok now that you have a house...… it's time for 48v option 2 build. Like as in a grid tied (at least "connectable" off grid) like 4-8Kw 240 / split phase system with LiFe battery bank! Come on Will, you know you want to do it :-)
The best advantage of a 48V system? Being able to connect to my golf cart batteries. Already purchased a well-used APC 3000XL UPS that I am using as an inverter. About to add four 100W panels and will have a self-propelled power station. Will be very handy when the next hurricane knocks out grid power.
You should next do a video on the techdirectclub nissan leaf batteries that at 48V. I think a lot of us would be interested to hear your thoughts on them. I was thinking of building a system with this unit and the 48V Nissal Leaf.
I am looking to build a 48v system in the nearest future and I am glad to see you have decided to make a video on more powerfull systems. A suggestion for possible future video: I have been looking at many 3000w+ inverters (for a house) and I am slightly confused about high frequency inverters and lower frequency inverters. Would love to hear your opinion on them. Thanks and keep up the great work. :)
Hey Will, if you’re ever looking to buy a 48V battery cells you can buy those from Humless. We buy their batteries all the time they come in 5kw increments. We install large 48v battery systems all time.
Your website is incredible too! Basically one stop shopping for the right system at the best price with options for several levels. That’s exactly what I need. Why bother with others that are more confusing or biased towards one system for which they make more profit. Plus, I can watch your videos about every option and learn why and how I should proceed. Indispensable information. Many thanks for demystifying solar energy.
I noticed the All-In-One ads indicate that some units have split-phase and true two-phase and that ganged units could be used for three-phase. I wonder how well this would work for getting three phase for a small machine shop, HVAC or water pumps?
Thank you so much.. I've always felt that getting higher power 300 + watt panels and connecting 24-48 would be much more advantageous. But I've been looking for cheaper modules.. and the one you've put up on the All in-one system.... Keep the great work.. and do a bit more with the 24/48 cheap solution..
Great Unit to have, I recently started with buying a tiny solar generator portable unit (XMUND XD-PS6) for less than 100 euros from Aliexpress. It has a 155Wh Li-ion battery pack (3.7v 14Ah) and has 4 USB outlets of which 1 is QC3.0 and 1 is USB-C. A built-in 100-150 Watt Inverter is for use with small appliances. It charges with an included 15v - 2A adapter or solar through a MPPT BMS at 2A max. So 30 watts input from an adapter or a tiny 30+ Watt Solar panel. It charges in 6-8 hours from 0-100%. What surprises me is that the MPPT BMS unit uses 30 Watt power from solar even if it's cloudy (behind glass in a bedroom) and if there is no direct sun at all. Approximately 1% an hour, great trickle charger.
Just a tip on terminals and not breaking screws, somewhere(hopefully) the torque recommendations are written in documentation or a search online might work, then you need to buy yourself a torque screwdriver and set it at the correct torque. These torque screwdrivers aren’t cheap but doing what your doing over and over it would be a good investment. I had a 3rd year apprentice snap every screw on maybe 50 terminals in a cubicle, when I asked him how he managed to snap them all he said that he thought you tightened until they snapped that way nobody can undo them and they stay put!!!!
Good helpful content, it’s a good idea to have another junction box or high amp main switch (away from your battery) and set it to open, then connect your last battery terminal, then close the circuit with your switch or junction. It is a rule you NEVER make a spark near a battery, any hydrogen leak from a battery (or vented battery in particular is extreme risk) will equal a decent explosion and a hospital stay. I used to do off grid power installations many years ago, some were 2 tons of batteries. Sealed batteries do have a valve and if overcharge current is too high that pressure valve will open.
I have an editing heads up for you. Your thumbnail has a red line around it. When scrolling, it triggers my mind to think that it's a progress bar showing that I've already watched the video.🖤
Great, i bought an old Server Rack UPS with 48v leads to a battery bank. It has a 100A fuse and can output 240v at 1600 Watts load (2200 VA). Not bad for a scrappy $20. The 8 small 12v 7A (NP7-12) valve regulated lead acid batteries are broken and i had to remove all 20KG worth of them from the rack. Very ingenious setup of 2 x ( 2 x (2 x 12v in parallell) in series) in series to get you to 48v 14A. No balancing here of-course. So i probably have to buy and put 2 x 24v AGM's or 4 x 12v AGM's in series after equalizing. I do know there is a balancer board for this kind of setups with a fifth battery. The cheapest thing to do is to buy 8 new small NP9-12 batteries leaving me with only 864 Wh (usage only 432 Wh) deep cycle. But i wanna ramp up to 48v 100 Ah = almost 5KWh full usable capacity. Is there an easy way to do this with Li-Ion (Phosphate) + BMS without problems with (Lead acid) charge & discharge cut-off voltages?
Thank you for your knowledge and thank you for making solar inverter talk understandable. This is for my house so I have to get up the nerve to get the 48 volt.
I am using 24v solar panels (330 watts x 2 = 660 watts) with MPPT charge controller to charge 140amp 12v flooded lead acid battery that powers my 12v dc appliances (ceiling fans, lights, laptop, pc, water pump). I do not have inverter yet. If I jump to 48v using step down dc-dc converter, how much energy will this dc-dc converter consume to do the job?
I gathered (from watching Weber auto videos) that you were safe from shocks on DC systems up to 70 volts, and on AC systems up to 50 volts. And this is the official advice of the SAE.
Hope you keep your RV and call it "The Solar Roller" and deck it out with demo solar systems you can take to events to teach people about solar. (all tax write off BTW)
This guy is awesome! I think "Sheldon's cousin" bc he is very well spoken and informative and best of all no BS. I showed this vid to my wife to try and get her on board with putting our chicken coop shed off grid instead of running 100 ft ext cord. So much cheaper to keep the cord but this looks so much cooler.
Hi Will, Your videos are terrific and you're a wonderful communicator! Been watching many diy solar youtubers for years and your channel presents complex subjects in relatively easy to understand ways. I'm slowly working towards an off grid system for a little shack I have in the Caribbean and found your most recent MPP 48 volt tutorial helpful. Can that MPP, from the AC out, connect directly to an electrical panel with circuit breakers? Keep that sharp mind humming. Best regards, D
So all you do is plug it into the mains and that can power the whole house providing there is enough sun, solar panels, and the inverter is big enough? If you exceed the load itll take the deficit from the grid?
My interest in 48v over 24v is the native 48v DC mini split Air Conditioners that are designed to run direct from panels to unit without an inverter. I would like an inverter and battery system for my Tiny houses, but have limited roof space for a small AC ‘s 1kw of panels so I want to combine these systems. Do you know anything about those systems?
@@joelhansen7373 I'm also interested, cutting out the @20% inverter loss would make A/C possible for me, but I've only found very expensive 48v mini split A/C designed to survive on salt-water yachts/sailboats, or some completely unknown units overseas where I doubt I'd find an English manual, much less customer support. Also, as a supplement to keep cool at night without insane batteries... I work for engineers, and they suggested I build a super insulated freezer, full (almost) of water with a car radiator/oil cooler inside, so that the extra juice from the panels freezes the radiator (aka heat-exchanger) inside a block of ice during the day. Then you flip a switch at night, and a 12v pump circulates antifreeze through the heat-exchanger in the freezer through insulated PEX water lines to another radiator/oil cooler near the bed, with a 12v fan blowing air over that cold radiator right to the bed. Then add an insulted door or thick hanging blankets to keep the cold air in the bed area. It wouldn't be that hard to rig a thermostat. You'd have to experiment to find out the best size for each component and the ideal pump rate. Sounds like a pain, but the only way to stay cool at night off grid around the Gulf of Mexico without winning the lottery. One of the engineers has this set up at his fishing cabin using a big deep chest freezer like you have in the garage (with extra insulation), since solar panels are cheap and batteries cost a fortune. He said that giant chunk of ice will freeze you out of the entire cabin no matter how hot and humid the night is.
You are FANTASTIC. I started watching b/c I am building my tiny house off grid, and you have INSPIRED me, and I have found several sources that will allow me to build my full system for under $3000!!!! That is w/ FULL battery bank! After discussion w. an electrician friend, looks like we might have a STARTUP! TYVM!
If you could be please show us on how to create a 24/48 volt solar Array using 100 watt panels.... but what I'd really like to see using 300+ watt panels... You have a great channel, I just started following you.. this is what I've been looking for.. Thanks
Hi Will, I like that you show that AGM batteries are an option, here in Puerto Rico, lipo batteries are still too expensive, solar panels are really cheap tho. Love how simple this video is.
Thank you Will for this insightful video, in fact I’ve been waiting for this opportunity as I’ve just bought the 5kW version PIP5048GK. I’ll be grateful if you or anyone could touch a bit on the fusing and circuit breaker aspects as well. Congratulations for your new home and project. I’m number one fan. Lol
Might want to put in a cutoff after the DC to AC convertor. This will allow you to separate the convertor from the rest of the system prior to any battery maintenance or battery replacement. Put in a cutoff prior to going into your fusebox in your home. I would put in a fuse prior to the DC to AC convertor. In case of a lightning strike, this will save you a dollar or two in replacement costs. Since you're in the UK, check with a certified solar technician to see what the local code states. That should give you more information. Good luck.
Plan on using solar power for long term grid out situations and for off grid as well. Problem is that industry has been slow to provide "plug and play" products. I feel that your video presentations are very informative but this one has caught my interest because of the simplicity of the system. Thank and a gret job.
Mind blown with the mobile solar power units. I see these as the go-to solution for RV/van life. So simple, small footprint, virtually plug and play. Thanks for the vids
Thanks for the video Will. These seem very simple to implement. For the AC output connection, can we have a dedicated breaker in the main panel or do we need a critical loads panel? I see this as a requirement for many hybrid inverter systems.
Yes a dedicated breaker panel is ideal. For this system, it is too small to need a breaker panel, but yes, that is the best way to do it. Will cover than in my house system
@@WillProwse sorry for bugging in here in the comments but I've got a serious question. How many of those small 10 amp cords for appliances should I wire in to this model to be able to use the full output load? I just need an opinion please, I trust your judgment.
I already bought the 12v 800watt mppsolar all in one and now in hindsight wishing I had bought the 24v 1600watt model for better results. But I’ll use the smaller one in a simple cargo trailer set up with one 12v 100ah liFePo battery. It never ends💰💰 Once solar grabs you it’s all over. Making my carbon footprint even smaller. 🤙
Thanks Will. How would a system like this relate to someone with panels that include microinverters? I was thinking of buying the newer panels with the 240 volt microinverters on each panel. These seem cheaper in the long run and easier to control.
Hi Will, awesome vid as always. If possible can do a vid on 18650 battery bank and solar panel for electric bicycle? i plan to use flexible solar panel to custom made to charge by battery for electric bike when riding.
Oh I avoid 18650 like the plague. Even if using cylindrical cell LiFePO4, better off using 22650. I hate all 18650 packs unless it's a Tesla module. For your application, a ready built nmc or nca pack might serve well. But yeah I'll see what I can do
excellent Solar power 48 V inverter electrical engineering & batteries series connection to increase the voltage & then connection of Solar panels , Grid power , & batteries to inverter # UR method of explanation is excellent # i LOVE it & its easy to understand # Thank U # smart young man #
i have tesla model s module and this brand inverter. i am however tapping into teslas own bms modules that are inside of the modules. for that i use jack rigter's / sen. massies ( see the evtv channel ) system...rather expensive , but truely worth it
@@squidlings Thanks for your response bud. I'll get a BMS. And yeah I'm planning to pair the batteries in series to create a 48 volt. I don't need a Battery Protect right since I'm gonna be using a BMS?
Will I have wanted to ask you hundreds of questions, but didn’t want to be a pain in the butt asking so many questions. so I just ordered your book. Boy Howdy buddy! Your book is so fantastic!! Not only explaining the different components of a solar system, but examples of how to calculate the proper sizes of each component in plain English for even dumb newbies like myself. I’m so excited about this book! Thanks for the excellent info! Keep up the great work and your excellent videos!! I’m an avid fan.
I just bought a new EzGo golf cart with a nice Lithium Ion battery I have plans on using when I go camping for our solar generator, this system should work perfect for this with 4 pcs of an 100 watt solar panels wired in series to charge the golf cart battery.
So if 24 cheaper than 12, 48 cheaper than 24 if you keep going higher and higher you end up that seller will pay you just to take his 1024 million volt solar panel away from him!
Hi. These 48 volt all-in-ones are the way to go for sure, especially since cost mainly lies with the batteries. A good way to budget that is with a 48 volt electric bike battery. This provides a cheap beginning setup where the battery can also be used for your bike, which is good since down the road when you're ready to upgrade your battery the bike battery will still be useful. Nothing worse than having lots of old but too-valuable-to-junk stuff lying around. Have any of that? My initial system will likely be one of the Growatt 3K, 8 100 watt flexibles using my install method, and the 18ah 48 volt bike battery I already have. When I buy a "real" battery I can get a second Growatt and have 240 volt capability. You've taught me a lot so far, kid.
I went for 24v system for my camper van because 48v equipment is so much harder to find. I designed it with 4 solar panes and 2 MPPT solar chargers and 4 Lithium 100Ah batteries with thicker cables so if needed in an emergency can I can reconfigure it to 12v or even 48v.
I have been looking into whole house solar, and getting a company to do it for you is usually cheaper since you can get State/Federal discounts and you have to pay a licensed electrician to do the grid tie stuff any way (where I live, your house is required to be on the grid). All companies I've talked to use micro inverters. Let me know what you think about this hypothetical setup: I have an exterior main breaker panel, from there it splits to 3 panels. One downstairs, one in the garage, and one in the detached shop. This is how the house was built 30+ years ago. Step 1: Get solar panels with micro inverters installed by a partner of my power company. With the Federal / State discount, resulting price is the same as or cheaper than I can buy and install the solar panels manually. Result would be a net metering device on the main exterior breaker panel. Step 2: Buy a MppSolar 5KW and 48v battery array and re-do the garage breaker panel so that the the 120v solar array (flowing through the normal house wiring) charges the batteries on the MppSolar, which then powers my kitchen, freezers, etc. Step 3: Repeat step 2 in the basement, which provides lighting etc for the rest of the house. Possibly repeat in the shop. I'd end up with 2 or 3 MppSolar 5KW units each with their own battery banks in different areas of the house. I wouldn't have DC charging on the batteries - only 120v. I don't think I'd be able to run the AC off of the batteries (which is okay) unless I tied 2 units together to get 240v. With many companies, the house power shuts off if the grid goes down - except for a single 120v line to the garage to power a Yeti (or something similar). If the solar company I go with is similar, then, after the install, I would extend that line and run dedicated lines to all the breaker boxes so that I could still have 120v into the MppSolar units when the grid is down. Depending on how the grid tie works, I might have to make it a manual switch over. One question is this: Would the 120v house power (from the solar or grid) be used 100% of the time unless the grid is down and it is night time? So the only 120v to 48v DC loss is a small float charge? Or, would the MppSolar inverter drain the batteries down to cut off before taking the 120v input line? Does that make sense? I would want the MppSolar units to only use the batteries if there was no power coming in on the 120v line. Assuming the last paragraph is possible, and assuming I use overkill gauge wire (not an extension cord) does this seem like a valid route to go to get whole house power (at a reasonable price) and be able to add batteries later? Sorry for being so long winded, I hope it was clear enough. Thanks.
Wow That Is Amazing! 12 24 48 Volt From RV To House Use! What A Transition! I Live In Florida And It Is Hurricane Prone This System Looks Like It Would Fit For Emergency Use! Thank You For The Video And Your Expertise! Nice!
Hello Mr. Prowse. Let me first say that you are a very smart and honest person. Second, you are great teacher. Third, I will probably end up in the hospital or burning down a building if I tried to do what you do (no matter how simple). Last, I see my electricity bill increasing. I will retire in 5 years and need to start planning. Using the 48v solar power system or some other one, which efficient appliances would you suggest to use for such a system. For example, I have a 1K sq ft. condo. Which mini-split system, refrigerator, stove, microwave? and washing machine might work with this solar power system? I apologize for asking the impossible. Thank you.
I'm not worried with getting shocked , but I'd still like one or two of these, I wired 480v battery chargers hot for years, I'd like a splitphase with these guys,
Nice job making easy & straight to the point videos (this is coming from an electrical engineer lol). I'm trying to find a solar solution to drive an electric hot water heater tank, but at ~4.5k to 5k watts, it would take a serious unit. Just bought a new house & it runs on oil, don't want to use oil for hot water lol. Planning on getting a wood stove too, because oil $ are about to get outrageous thanks to our new leadership in this country 😔
When you say "you can not mess these up" really should be said "Don't mix these up" or "be sure not to mix these up" it is a small thing but someone paying less attention than they should could hear the they can't be mix up - like fool proof. Yes you do a good job of warning other wise that you could get shocked but the wording could be work on just a bit. Thank you for all your videos they are very helpful and inspiring.
Thanks for the video, I think that in the RV world, the maximum voltage is 24V DC, especially with the use of lithium batteries, since they accept high charge and discharge currents, there are no problems as for the lead technology, using the 12 / 24V DC is useful for directly powering anything designed for RV without the use of an inverter or DC converter. The maximum human contact voltage allowed in Italy, considered to be safety, is ≤ 50 V peak alternating voltage or ≤ 120 V peak continuous voltage. Under these voltages they are called very low voltage, above it starts the low voltage, (considered dangerous) ranging from> 50V to 1000V AC - and from 120V DC to 1.500V DC. Ciao
@joann robinson yes but the concept is very broad, in dangerous areas, not in civil environments where 12 or 24 Volts are generally used, in all cases it is also possible to use 48V AC but on condition that the transformer has double safety isolation with specifications according to the law, it is not enough to switch off the 48v voltage with a normal transformer

Congrats on your new home and studio!
I like the idea of using a Tesla battery... CAN I USE a SYSTEM LIKE THIS FOR IT"S BMB?
????????????????????????
Did you mention the cost?
What is the price of for this unit,and of the two what is the one you showed?
also what happens when you no grid for it to to go to when full?
Didn’t read or hear anything said on the type of inverter, modify or pure sine ?
Another update! I am moving into a house that I just bought and building a huge testing labratory/film studio. I will have some really awesome systems and explanation videos coming :) I am a bit behind on videos right now for this reason, but will be uploading a lot more in the weeks to come. Stay tuned :D
DIY Solar Power with Will Prowse awesome dude, really happy for your recent success you obviously doing something right
how nice will!!!
Cool video suggestion: when then battery is attached; there is a spark. Even if you use a switch, there's internal current surge. I think there's a capacitor charging. So if we all used a resistor and diode properly attached, the sparking and current surge that's bad for electronic boards could be eliminated. That woul be an awesome video and Gizmo to sell from your website. Thanks Jack
Congrats, Will. I've been hoping your vids might start moving that direction---DIY home systems. Great! Looking forward to your future vids even more now!
We are with you.
I'm part of a couple off-grid facebook groups. Any time someone posts a question about solar, everyone responds with links to your videos. I can't think of another channel that comes close to being as thorough or comprehensive. Thank you
You are one of the best teachers of solar on RUclips. I love your videos! Thanks
Pls can I use 12v inverter to charge 4 batteries of 150ams
If you had a solar installation company I would totally buy its services! Will you are such an honest and quality focused person. Thank you for your videos!
Me too!
Its great the market is creating these quality easy to install systems. It shows the marketplace is maturing and solar is becoming even more accessible and accepted.
Hello l just discovered your channel that's amazing to follow but l have a question is about my house not in America but outside how many solar panels l need for 4 rooms including yard front house tell me please how many watts and batteries generally explain me for all how many powers
I have been researching solar for about a year now contemplating a grid tied system for our house and to charge my Chevy Volt. The all in one systems are making this look so doable without the hassle of picking components, getting them wired and then commissioning the system. I've been a technology professional for 25 years so I can appreciate complexity, but simpler is definitely better in this case! Keep up the informative easy to follow videos that have become my go to source for DIY solar/battery systems. Looking forward to the larger 5k system review.
u impart more knowledge in 5 mins than I've gotten in 5 hrs from university based 'solar' seminars
University is a scam, especially anything environmentally conscious.
Grab a 1 ohm 25 watt resistor to arrest the spark when connecting batteries to the inverter unit. It's kinder to the capacitors in the inveter. Put the resistor inline for 5 seconds, then move the battery cable to the battery terminal, and throw the resistor in a drawer for the next inverter you plan to play with :)
can you power up small window ac 3/4 to 1 1/2 hp with that?
Or use a small 120v bulb when it dims out wham charged capacitors no spark
Hey dash8brj! Thanks for the tip! Sorry for my bad english but i did not get it when you said inline for five seconds. Could you explain that? Inline means between the battery positive and the positive wire? Thank you so much!
Some inverters, PSUs, and other gear sometimes do have internal inrush current protection. These are usually done using a resistor in series, and a bypass relay, that energizes only after unit charged capacitors enough. It is usually just using few seconds delay. If the unit doesn't have it, I recommend sticking a DC two disconnect switches in parallel, and one of them via the resistor. Definitively good to have if you have very big system or you plan to be changing batteries frequently, and stuff.

There are a lot of youtubers making solar power vids, but this guy has a super likeable character. He seems like humble and approachable person.
I want to create a little solar system with my 12 yr old daughter to give her some experience. This might be something we can use to create an off grid bedroom to run her electronics. Very cool.
Oh that would be fun! Start with 24v for first system though. Super safe voltage to work with.
"And here's the batteries we'll be getting. No, you only need two. No you can't get ten. Because you're not going to be playing video games all night. Because I said so!"
Mazlem I love it!
Im so glad i watched this before going out and buying all the separate components.
I purchased the MPP 2400w model, and I can't wait to get started on my solar build. Just saving up for those Battleborns. Will, your passion for Solar arrays has helped so many people. Thank you for all of the great information.
So glad I found your channel, finally understanding how solar works.
I usually add a battery cut off switch which helps avoid the spark :) Great to see a 48v system!
High voltage dc switch (300v or higher so the dc arc is arrested without burning out the connector)
I do not like battery cut off switches because if someone switches the switch to open, and the unit is connected to a string of panels, it can destroy the mppt board. I prefer hardwire battery, and switch at the panels for maintenance.
Yes exactly! Some switches cannot handle that spark and will damage it..same with a lot of power connectors. Exactly
@@WillProwse That's a good point. How do grid tied systems deal with this? The types that feed back into the grid. They can be shut off at any time by the electric company.
@@JamesMorrin net metering
Might be wise to mention the AC cable size requirement for full load. Minimum 16 gauge for the 120V size and it will probably warm up and is only going to be good for a very short run. For instance the 16 gauge cord you are using is only rated up to 13 amps most of the time, 2600 watts @ 120V is closer to 22 amps. If you are going to be using full load 10 gauge is a much better idea and the power outlet you plug that in to if you will potentially be pulling over 2600 watts from the grid should be a 30 amp breaker with a cord and outlets to match. When you start using the systems you not only have to calculate the loads the system can handle and the wire size for the DC side but also the AC side under full load. That system can power a decent sized RV that likely has a 30 Amp cord. Would hate to hear of someone burning their home or shop down due to undersized AC cords.
Great point! So true
I figure it is implied but this is a beginner video. I do assume that beginners understand wire gauge size for their loads, but always a great idea to mention it in these videos. thanks John
@@WillProwse Yeah, it might be worth mentioning though that the person doing the work should look up the wire sizes needed for their loading. It's hard to believe what some people will try and run through a little 18 gauge cord. People with electricity are like cats and boxes, if it fits it works...
10/3 extension cord cut offs
Do u mind giving me some deets on wiring size @john I would pay for it just trying to make sure I wire up correctly
I wonder how old this guy is. For the look of age this guy is so mature, confident and knowledgible.
I believe he is 26 years old and makes almost all of his money off of the youtube videos. He was surprised that I have 10 college degrees and he has none. He was very polite when we comunicated.
At the start i had a 12 volt system , then at the end went 48v for the main reasons that it runs a lot more efficient and cool , the amp draw is alot easier on the system ...
Perfect. Stand alone, no ‘daily ‘supply fee.’ ( connected fee from utilities: regardless of using it or not ). AC in can be a small cheap ‘stand alone ‘ generator to boost a low battery supply. 👍
12 years ago we bought a small 1300sf home with a basement and walk-in attic. I bought a 220w 12-18 volt DC and a 400w wind turbine. I also bought 12- group 31 deep-cycle batteries. The panel, turbine, and batteries were 40 ft from the house. I ran a + and - run using 4ga high-strand wier about a foot underground through 1.5 pvc s40 to the house where I had a 8 block fuse box and 2 3000w TS-inverts. in the basement, I then wired a 110 plugin ever-room and 2 110 in the living room. We used the13w=75 watt 110 bulbs in each light we used the most at night and in the kitchen we used/installed 12v under cabinet RV light under all the cabinets. The house box was never touched and the battery power was independent. At that time it cost me $3,100 and we have been saving a 3rd of our elect bill since and without changing our lifestyle or habits. O, I also run most of all my shop radios, bench, equipment as well
Please do video that shows how to do a van conversion setup with this where you need 12v and 110v, how do the wires get attached and wall plugs/sockets light switch etc
Ok will do
@@WillProwse thank you
Thanks that's a great idea
i got shocked with 220 the other day wasn't all that bad, accidental touch real quick, working on a/c condenser motor, got it working by watching these videos.
Will, please talk about using Nissan Leaf batteries in conjunction with these controllers in 48 volts to use in home systems. This channel is awesome and very helpful. No bs just facts and real world approach....thanks .
A Day where in Texas do you live?
I’m just outside San Antonio
Very educational. You're helping retired seniors to improved their van /home with solar information. God bless you
More people are adding super capacitors to their PV system to help in the initial motor startup load. Can you explore and make a video? Thanks.
This video has helped me lots. I am going to be building a 48v system for my house. I am terminally ill the system isn't for me its for my family after I pass away I want to make sure my family is well cared for regardless of what happens in the future they will have the power to run our home all the time that's what's important to me. Thanks much!!
We missed you Will! Even a proof of life, five minute video, is better than no Will for a week.
Ok now that you have a house...… it's time for 48v option 2 build. Like as in a grid tied (at least "connectable" off grid) like 4-8Kw 240 / split phase system with LiFe battery bank! Come on Will, you know you want to do it :-)
+1 I would love to see it...
The best advantage of a 48V system? Being able to connect to my golf cart batteries. Already purchased a well-used APC 3000XL UPS that I am using as an inverter. About to add four 100W panels and will have a self-propelled power station. Will be very handy when the next hurricane knocks out grid power.
That's smart!
You should next do a video on the techdirectclub nissan leaf batteries that at 48V. I think a lot of us would be interested to hear your thoughts on them.
I was thinking of building a system with this unit and the 48V Nissal Leaf.
I am looking to build a 48v system in the nearest future and I am glad to see you have decided to make a video on more powerfull systems.
A suggestion for possible future video:
I have been looking at many 3000w+ inverters (for a house) and I am slightly confused about high frequency inverters and lower frequency inverters. Would love to hear your opinion on them. Thanks and keep up the great work. :)
Great question on lf vs hf inverters, will do
Hey Will, if you’re ever looking to buy a 48V battery cells you can buy those from Humless. We buy their batteries all the time they come in 5kw increments. We install large 48v battery systems all time.
Review wind turbines.
I wanna see you use wind turbines since they compliment solar.
Your website is incredible too! Basically one stop shopping for the right system at the best price with options for several levels. That’s exactly what I need. Why bother with others that are more confusing or biased towards one system for which they make more profit. Plus, I can watch your videos about every option and learn why and how I should proceed. Indispensable information. Many thanks for demystifying solar energy.
Good work will. Congrats on buying your house. I’m very happy for you. You have a really good channel that I endorse. Keep up the good work.
thanks to your video i purchased a lv5048 and am exited to set it up...it would be nice to see you setup a whole house system in your new home !!!
I noticed the All-In-One ads indicate that some units have split-phase and true two-phase and that ganged units could be used for three-phase. I wonder how well this would work for getting three phase for a small machine shop, HVAC or water pumps?
This young man is an absolute trip! Nice to see the enthusiasm!
Thank you so much.. I've always felt that getting higher power 300 + watt panels and connecting 24-48 would be much more advantageous. But I've been looking for cheaper modules.. and the one you've put up on the All in-one system.... Keep the great work.. and do a bit more with the 24/48 cheap solution..
Great Unit to have, I recently started with buying a tiny solar generator portable unit (XMUND XD-PS6) for less than 100 euros from Aliexpress. It has a 155Wh Li-ion battery pack (3.7v 14Ah) and has 4 USB outlets of which 1 is QC3.0 and 1 is USB-C. A built-in 100-150 Watt Inverter is for use with small appliances. It charges with an included 15v - 2A adapter or solar through a MPPT BMS at 2A max. So 30 watts input from an adapter or a tiny 30+ Watt Solar panel. It charges in 6-8 hours from 0-100%. What surprises me is that the MPPT BMS unit uses 30 Watt power from solar even if it's cloudy (behind glass in a bedroom) and if there is no direct sun at all. Approximately 1% an hour, great trickle charger.

Just a tip on terminals and not breaking screws, somewhere(hopefully) the torque recommendations are written in documentation or a search online might work, then you need to buy yourself a torque screwdriver and set it at the correct torque. These torque screwdrivers aren’t cheap but doing what your doing over and over it would be a good investment. I had a 3rd year apprentice snap every screw on maybe 50 terminals in a cubicle, when I asked him how he managed to snap them all he said that he thought you tightened until they snapped that way nobody can undo them and they stay put!!!!
Fantastic video, thank you for taking the time and expense to make it.
Good helpful content, it’s a good idea to have another junction box or high amp main switch (away from your battery) and set it to open, then connect your last battery terminal, then close the circuit with your switch or junction.
It is a rule you NEVER make a spark near a battery, any hydrogen leak from a battery (or vented battery in particular is extreme risk) will equal a decent explosion and a hospital stay.
I used to do off grid power installations many years ago, some were 2 tons of batteries.
Sealed batteries do have a valve and if overcharge current is too high that pressure valve will open.
I have an editing heads up for you. Your thumbnail has a red line around it. When scrolling, it triggers my mind to think that it's a progress bar showing that I've already watched the video.🖤
Oh I did that on purpose but didn't realize it would show up like that! Thanks. Sorry about that
Great, i bought an old Server Rack UPS with 48v leads to a battery bank. It has a 100A fuse and can output 240v at 1600 Watts load (2200 VA). Not bad for a scrappy $20. The 8 small 12v 7A (NP7-12) valve regulated lead acid batteries are broken and i had to remove all 20KG worth of them from the rack. Very ingenious setup of 2 x ( 2 x (2 x 12v in parallell) in series) in series to get you to 48v 14A. No balancing here of-course. So i probably have to buy and put 2 x 24v AGM's or 4 x 12v AGM's in series after equalizing. I do know there is a balancer board for this kind of setups with a fifth battery. The cheapest thing to do is to buy 8 new small NP9-12 batteries leaving me with only 864 Wh (usage only 432 Wh) deep cycle. But i wanna ramp up to 48v 100 Ah = almost 5KWh full usable capacity. Is there an easy way to do this with Li-Ion (Phosphate) + BMS without problems with (Lead acid) charge & discharge cut-off voltages?
Don’t forget about perhaps the biggest benefit of higher voltage - far better inverter efficiency.
Indeed!
@@WillProwse I'd love to hear some numbers on that to better understand the actual efficiency gains with a 24 or 48 volt system.
Check out my post about my real World results of living with this 48 V system for a few years before you make the same mistake that I made.

@@joelhansen7373 the comment is on this video somewhere.
Thank you for your knowledge and thank you for making solar inverter talk understandable. This is for my house so I have to get up the nerve to get the 48 volt.
I know I am waiting for you to do some grid-tied home systems. Something for those of us who cannot afford to just pay for all new Tesla stuff.

That would be most helpfull
Can’t wait till you do a 12000 Growatt 48 volt post. Regards from down under 🇦🇺
You’re extremely passionate and this will make you a rockstar
I am using 24v solar panels (330 watts x 2 = 660 watts) with MPPT charge controller to charge 140amp 12v flooded lead acid battery that powers my 12v dc appliances (ceiling fans, lights, laptop, pc, water pump). I do not have inverter yet. If I jump to 48v using step down dc-dc converter, how much energy will this dc-dc converter consume to do the job?
Good ones are 98%+ efficient...
I gathered (from watching Weber auto videos) that you were safe from shocks on DC systems up to 70 volts, and on AC systems up to 50 volts.
And this is the official advice of the SAE.
Hope you keep your RV and call it "The Solar Roller" and deck it out with demo solar systems you can take to events to teach people about solar. (all tax write off BTW)
Great Idea and suggestion!!!
This guy is awesome! I think "Sheldon's cousin" bc he is very well spoken and informative and best of all no BS. I showed this vid to my wife to try and get her on board with putting our chicken coop shed off grid instead of running 100 ft ext cord. So much cheaper to keep the cord but this looks so much cooler.
Hi Will, Your videos are terrific and you're a wonderful communicator! Been watching many diy solar youtubers for years and your channel presents complex subjects in relatively easy to understand ways. I'm slowly working towards an off grid system for a little shack I have in the Caribbean and found your most recent MPP 48 volt tutorial helpful. Can that MPP, from the AC out, connect directly to an electrical panel with circuit breakers? Keep that sharp mind humming. Best regards, D
You are a wonderful teacher,even a novist like me understood your lesson. Thank You so much!
So all you do is plug it into the mains and that can power the whole house providing there is enough sun, solar panels, and the inverter is big enough? If you exceed the load itll take the deficit from the grid?
This is looking ideal, and it looks like they come for 240v also. Congratulations on the house!
My interest in 48v over 24v is the native 48v DC mini split Air Conditioners that are designed to run direct from panels to unit without an inverter. I would like an inverter and battery system for my Tiny houses, but have limited roof space for a small AC ‘s 1kw of panels so I want to combine these systems. Do you know anything about those systems?
Wow good point. Can't comment on that but I sure am interested in looking into that. Thanks
Add my name to the list of those VERY INTERESTED in a 48V mini split AC system!
I have an idea on these systems. I'm a Solar system installer
gham elvis - I’m very curious about your ideas. I just bought an old bus with no solar & no air so I’m motivated!
@@joelhansen7373 I'm also interested, cutting out the @20% inverter loss would make A/C possible for me, but I've only found very expensive 48v mini split A/C designed to survive on salt-water yachts/sailboats, or some completely unknown units overseas where I doubt I'd find an English manual, much less customer support.
Also, as a supplement to keep cool at night without insane batteries... I work for engineers, and they suggested I build a super insulated freezer, full (almost) of water with a car radiator/oil cooler inside, so that the extra juice from the panels freezes the radiator (aka heat-exchanger) inside a block of ice during the day. Then you flip a switch at night, and a 12v pump circulates antifreeze through the heat-exchanger in the freezer through insulated PEX water lines to another radiator/oil cooler near the bed, with a 12v fan blowing air over that cold radiator right to the bed. Then add an insulted door or thick hanging blankets to keep the cold air in the bed area. It wouldn't be that hard to rig a thermostat. You'd have to experiment to find out the best size for each component and the ideal pump rate. Sounds like a pain, but the only way to stay cool at night off grid around the Gulf of Mexico without winning the lottery. One of the engineers has this set up at his fishing cabin using a big deep chest freezer like you have in the garage (with extra insulation), since solar panels are cheap and batteries cost a fortune. He said that giant chunk of ice will freeze you out of the entire cabin no matter how hot and humid the night is.
You are FANTASTIC. I started watching b/c I am building my tiny house off grid, and you have INSPIRED me, and I have found several sources that will allow me to build my full system for under $3000!!!! That is w/ FULL battery bank! After discussion w. an electrician friend, looks like we might have a STARTUP! TYVM!

Best infromation on your channel !!! Super channel !
Hi Will, I like that you show that AGM batteries are an option, here in Puerto Rico, lipo batteries are still too expensive, solar panels are really cheap tho. Love how simple this video is.
I want to learn how to make my own high quality battery
Top notch btw, sharing everywhere.
I barely understand, but I’m hooked and will watch all of Will’s videos..Bought the book. Someday I will hook up a system 🎯
Thank you Will for this insightful video, in fact I’ve been waiting for this opportunity as I’ve just bought the 5kW version PIP5048GK. I’ll be grateful if you or anyone could touch a bit on the fusing and circuit breaker aspects as well.
Congratulations for your new home and project. I’m number one fan. Lol
Where did you purchase it? Is it 120 or you need a step down transformer?
@James Edwards I bought it off eBay for £530. It’s a 48v System, exactly what I need so I don’t require a step down transformer. Thanks
Can you send me link.
I'm in the Bahamas
I bought it off solar_camper or search for pip5048gk on eBay uk. Hope this helps. Good luck
Might want to put in a cutoff after the DC to AC convertor. This will allow you to separate the convertor from the rest of the system prior to any battery maintenance or battery replacement. Put in a cutoff prior to going into your fusebox in your home. I would put in a fuse prior to the DC to AC convertor. In case of a lightning strike, this will save you a dollar or two in replacement costs. Since you're in the UK, check with a certified solar technician to see what the local code states. That should give you more information. Good luck.
Plan on using solar power for long term grid out situations and for off grid as well. Problem is that industry has been slow to provide "plug and play" products.
I feel that your video presentations are very informative but this one has caught my interest because of the simplicity of the system.
Thank and a gret job.
You rock Will! Love how you explain stuff!
Mind blown with the mobile solar power units. I see these as the go-to solution for RV/van life. So simple, small footprint, virtually plug and play. Thanks for the vids
Thanks for the video Will. These seem very simple to implement. For the AC output connection, can we have a dedicated breaker in the main panel or do we need a critical loads panel? I see this as a requirement for many hybrid inverter systems.
Yes a dedicated breaker panel is ideal. For this system, it is too small to need a breaker panel, but yes, that is the best way to do it. Will cover than in my house system
@@WillProwse sorry for bugging in here in the comments but I've got a serious question. How many of those small 10 amp cords for appliances should I wire in to this model to be able to use the full output load? I just need an opinion please, I trust your judgment.
I already bought the 12v 800watt mppsolar all in one and now in hindsight wishing I had bought the 24v 1600watt model for better results. But I’ll use the smaller one in a simple cargo trailer set up with one 12v 100ah liFePo battery. It never ends💰💰
Once solar grabs you it’s all over. Making my carbon footprint even smaller. 🤙
Thanks Will. How would a system like this relate to someone with panels that include microinverters? I was thinking of buying the newer panels with the 240 volt microinverters on each panel. These seem cheaper in the long run and easier to control.
You are a god send i hand no idea these existed. I m putting a 24v system in my van in a few weeks
Hi Will, awesome vid as always. If possible can do a vid on 18650 battery bank and solar panel for electric bicycle? i plan to use flexible solar panel to custom made to charge by battery for electric bike when riding.
Oh I avoid 18650 like the plague. Even if using cylindrical cell LiFePO4, better off using 22650. I hate all 18650 packs unless it's a Tesla module. For your application, a ready built nmc or nca pack might serve well. But yeah I'll see what I can do
I love your enthusiasm in the way you present everything. MPP Solar should be give you commission!
What panels do you run with this 48V system? Polycrystalline or Monocrystalline? Thank you!
excellent Solar power 48 V inverter electrical engineering & batteries series connection to increase the voltage & then connection of Solar panels , Grid power , & batteries to inverter # UR method of explanation is excellent # i LOVE it & its easy to understand # Thank U # smart young man #
can I use this for the tesla batteries? If so, do I have to use a BMS? Thanks
Yes. Research batrium. Tesla batteries are called 18650's
i have tesla model s module and this brand inverter.
i am however tapping into teslas own bms modules that are inside of the modules.
for that i use jack rigter's / sen. massies ( see the evtv channel ) system...rather expensive , but truely worth it
Just bear in mind a full tesla module is 24v so youd need a 24v inverter and work out a safe way to use the bms.
@@squidlings Thanks for your response bud. I'll get a BMS. And yeah I'm planning to pair the batteries in series to create a 48 volt. I don't need a Battery Protect right since I'm gonna be using a BMS?
@@houseofancients hello bud. May I see a detailed picture of your setup please? Thanks
Will I have wanted to ask you hundreds of questions, but didn’t want to be a pain in the butt asking so many questions. so I just ordered your book. Boy Howdy buddy! Your book is so fantastic!! Not only explaining the different components of a solar system, but examples of how to calculate the proper sizes of each component in plain English for even dumb newbies like myself. I’m so excited about this book! Thanks for the excellent info! Keep up the great work and your excellent videos!! I’m an avid fan.
Glad you like the book :)
I swear this guy is the “Michael Jordan” of explaining things.
Excellent analogy!
I just bought a new EzGo golf cart with a nice Lithium Ion battery I have plans on using when I go camping for our solar generator, this system should work perfect for this with 4 pcs of an 100 watt solar panels wired in series to charge the golf cart battery.
Batteries play an important role in energy independence, ENP51100 is the right choice for home energy storage compatible with major invertors
So if 24 cheaper than 12, 48 cheaper than 24 if you keep going higher and higher you end up that seller will pay you just to take his 1024 million volt solar panel away from him!
Voidex lol good one
Thank you, looking to power a 48v water heater and after watching, looking at power our little house, cheers great vids
Hi. These 48 volt all-in-ones are the way to go for sure, especially since cost mainly lies with the batteries. A good way to budget that is with a 48 volt electric bike battery. This provides a cheap beginning setup where the battery can also be used for your bike, which is good since down the road when you're ready to upgrade your battery the bike battery will still be useful. Nothing worse than having lots of old but too-valuable-to-junk stuff lying around. Have any of that?
My initial system will likely be one of the Growatt 3K, 8 100 watt flexibles using my install method, and the 18ah 48 volt bike battery I already have. When I buy a "real" battery I can get a second Growatt and have 240 volt capability.
You've taught me a lot so far, kid.
Looking forward to the larger inverter video - and hoping you show an example of using 18650's for a 48V battery system hooked up to it!
I really like the videos and wish to have my hands on the systems. I'm in South Africa and I really like to thank you for the step by step guide.
Thank you I am a novice and appreciate your time five stars
I went for 24v system for my camper van because 48v equipment is so much harder to find. I designed it with 4 solar panes and 2 MPPT solar chargers and 4 Lithium 100Ah batteries with thicker cables so if needed in an emergency can I can reconfigure it to 12v or even 48v.
I have been looking into whole house solar, and getting a company to do it for you is usually cheaper since you can get State/Federal discounts and you have to pay a licensed electrician to do the grid tie stuff any way (where I live, your house is required to be on the grid). All companies I've talked to use micro inverters.
Let me know what you think about this hypothetical setup:
I have an exterior main breaker panel, from there it splits to 3 panels. One downstairs, one in the garage, and one in the detached shop. This is how the house was built 30+ years ago.
Step 1: Get solar panels with micro inverters installed by a partner of my power company. With the Federal / State discount, resulting price is the same as or cheaper than I can buy and install the solar panels manually. Result would be a net metering device on the main exterior breaker panel.
Step 2: Buy a MppSolar 5KW and 48v battery array and re-do the garage breaker panel so that the the 120v solar array (flowing through the normal house wiring) charges the batteries on the MppSolar, which then powers my kitchen, freezers, etc.
Step 3: Repeat step 2 in the basement, which provides lighting etc for the rest of the house. Possibly repeat in the shop.
I'd end up with 2 or 3 MppSolar 5KW units each with their own battery banks in different areas of the house. I wouldn't have DC charging on the batteries - only 120v.
I don't think I'd be able to run the AC off of the batteries (which is okay) unless I tied 2 units together to get 240v.
With many companies, the house power shuts off if the grid goes down - except for a single 120v line to the garage to power a Yeti (or something similar). If the solar company I go with is similar, then, after the install, I would extend that line and run dedicated lines to all the breaker boxes so that I could still have 120v into the MppSolar units when the grid is down. Depending on how the grid tie works, I might have to make it a manual switch over.
One question is this: Would the 120v house power (from the solar or grid) be used 100% of the time unless the grid is down and it is night time? So the only 120v to 48v DC loss is a small float charge? Or, would the MppSolar inverter drain the batteries down to cut off before taking the 120v input line? Does that make sense? I would want the MppSolar units to only use the batteries if there was no power coming in on the 120v line.
Assuming the last paragraph is possible, and assuming I use overkill gauge wire (not an extension cord) does this seem like a valid route to go to get whole house power (at a reasonable price) and be able to add batteries later?
Sorry for being so long winded, I hope it was clear enough.
Thanks.
Wow That Is Amazing! 12 24 48 Volt From RV To House Use! What A Transition! I Live In Florida And It Is Hurricane Prone This System Looks Like It Would Fit For Emergency Use! Thank You For The Video And Your Expertise! Nice!
Hello Mr. Prowse. Let me first say that you are a very smart and honest person. Second, you are great teacher. Third, I will probably end up in the hospital or burning down a building if I tried to do what you do (no matter how simple). Last, I see my electricity bill increasing. I will retire in 5 years and need to start planning. Using the 48v solar power system or some other one, which efficient appliances would you suggest to use for such a system. For example, I have a 1K sq ft. condo. Which mini-split system, refrigerator, stove, microwave? and washing machine might work with this solar power system? I apologize for asking the impossible. Thank you.
I'm not worried with getting shocked , but I'd still like one or two of these, I wired 480v battery chargers hot for years, I'd like a splitphase with these guys,
Nice job making easy & straight to the point videos (this is coming from an electrical engineer lol).
I'm trying to find a solar solution to drive an electric hot water heater tank, but at ~4.5k to 5k watts, it would take a serious unit. Just bought a new house & it runs on oil, don't want to use oil for hot water lol. Planning on getting a wood stove too, because oil $ are about to get outrageous thanks to our new leadership in this country 😔
I use mpp solar 24v inverter in my house off grid its just awesome.
When you say "you can not mess these up" really should be said "Don't mix these up" or "be sure not to mix these up" it is a small thing but someone paying less attention than they should could hear the they can't be mix up - like fool proof. Yes you do a good job of warning other wise that you could get shocked but the wording could be work on just a bit. Thank you for all your videos they are very helpful and inspiring.
Right on. Very helpful. You are all about independent power 👍
Thanks for the video, I think that in the RV world, the maximum voltage is 24V DC, especially with the use of lithium batteries, since they accept high charge and discharge currents, there are no problems as for the lead technology, using the 12 / 24V DC is useful for directly powering anything designed for RV without the use of an inverter or DC converter.
The maximum human contact voltage allowed in Italy, considered to be safety, is ≤ 50 V peak alternating voltage or ≤ 120 V peak continuous voltage.
Under these voltages they are called very low voltage, above it starts the low voltage, (considered dangerous) ranging from> 50V to 1000V AC - and from 120V DC to 1.500V DC.
Ciao
@joann robinson Yes up to 60V DC, peak 120V DC, in AC logically it is less, in us the lowest alternating voltage is the European standard 230V 50Hz
@joann robinson yes but the concept is very broad, in dangerous areas, not in civil environments where 12 or 24 Volts are generally used, in all cases it is also possible to use 48V AC but on condition that the transformer has double safety isolation with specifications according to the law, it is not enough to switch off the 48v voltage with a normal transformer
